Topological Metal of NaBi with Ultralow Lattice Thermal Conductivity and Electron-phonon Superconductivity
Topological Metal of NaBi with Ultralow Lattice Thermal Conductivity and Electron-phonon Superconductivity
By means of first-principles and ab initio tight-binding calculations, we found that the compound of NaBi is a three-dimensional non-trivial topological metal. Its topological feature can be confirmed by the presence of band inversion, the derived effective Z2 invariant and the non-trivial surface states with the presence of Dirac cones. …
